Natasha Bedingfield has said she insists her managers arrange her tour schedule to give her enough time off to sleep in between shows and appearances.

She said recently: “If I don’t have eight hours, I’m an absolute nightmare - a wreck. This time around I’ve told everyone that if they only give me four hours sleep a night I’ll change into a different person.”

“The road is hard. There’s less stamina as a woman, which I didn’t want to admit to. I want to work as tough as any guy, but I have to pace myself.”
